Sometimes running program in Unix will fail without any debugging info or warnings because of the laziness of programmer.. So if need to find the right place where the program stops and start debugging right from there, set the coredump file size to…

Although SQL Server's Full-Text search is good for searching text that is within a database, there are better ways of implementing search if the text is less-well structured, or comes from a wide variety of sources or formats. Ryszard takes ElasticSe…
In this post we will integrate Apache Tiles 3 with Spring MVC 4, using annotation-based configuration. Apache Tiles is a template based, composite view framework: it allows to reuse page pieces across the application, keeping consistent look and feel…
1. gdb structure at the largest scale,GDB can be said to have two sides to it:1. The "symbol side" is concerned with symbolic information about the program. Symbolic information includes function and variable names and types, linenumbers, machin…
在emacs 里使用gdb emacs speedbar功能介绍 semantic功能介绍 上面3篇文章精华,都汇总到下面的.emacs文件里了. ;;启动semantic功能 (semantic-mode 1) ;;当光标移到到某个函数调用的地方,或者变量使用的地方的时候, ;;函数的原型(返回值,参数),变量的类型,会显示在emacs最下面的辅助入力区 (global-semantic-idle-summary-mode) ;;启动代码补齐的功能 (global-semantic-idle-…
1.调试原理 GDB调试是应用程序在开发板上运行,然后在PC机上对开发板上得应用程序进行调试,PC机运行GDB,开发板上运行GDBServer.在应用程序调试的时候,pc机上的gdb向开发板上的GDBServer发出命令,而开发板上的gdbserver就会向应用程序发出信号,使应用程序停下来或者完成其他一些工作. 2.安装GDB和GDBServer(gdb-7.4.tar.bz2 ) 2.1.GDB 1.下载: http://ftp.gnu.org/gnu/gdb/  2.解压:tar xvf…
网络上已经有很多gdb调试的文章了,为什么我还要写这篇文章呢,因为本文是写给gdb新手的,目的就是通过一个简单的例子来让新手很快上手.一旦上手入门了,其他的问题就可以自己去搜索搞定了.右边是gdb的Logo,为啥是条吹泡泡的小鱼呢?我也不懂啊.   本文的例子基于以下代码 main.c: #include <stdio.h> 2 void print_str(char* str){ printf("%s", str); str[] = 'a'; printf("\…
多线程调试之痛 调试器(如VS2008和老版GDB)往往只支持all-stop模式,调试多线程程序时,如果某个线程断在一个断点上,你的调试器会让整个程序freeze,直到你continue这个线程,程序中的其他线程才会继续运行.这个限制使得被调试的程序不能够像真实环境中那样运行--当某个线程断在一个断点上,让其他线程并行运行. GDBv7.0引入的non-stop模式使得这个问题迎刃而解.在这个模式下, 当某个或多个线程断在一个断点上,其他线程仍会并行运行 你可以选择某个被断的线程,并让它继续运…
